I have had this question on a test before!! Hope this helps
Small bodies from which the planets are formed is called : Planetesimal.
Planetesimals that have survived to the current day are valuable to scientists since they contain information about the Solar System's formation.
Answer:
Balanced Eqn
2C2H6 + 7O2 = 4CO2 + 6H2O
From the balanced equation
2((2*12)+(1*6)) of Ethane gave 6((1*2)+16)) of water
60g of Ethane. >. 108g. Of water
Xg > 1.61
X= 1.61*60/108
X= 0.89g
(g).
That is the symbol typically put next to elements as a subscript to indicate that an element is a gas.
For instance, H2(g).
Symbols vary for other states of matter and etc.
Hope this helps!
